AReferring 'to the drawingsby reference characters in whichlikecharact'ers designate like; parts, 11` designates the heating device as an entirety.V The devicell*comprises` interrelated, vdetachable,4 and relatively adjustable fsections i12 land i 13 which` are preferably contion 26 adapted for projection within section 22 forming ai guide therefor.

structed ofrlightsheet metal-infany desired manner. The section 12 comprises a bottom 145 sides 15, a sloping top 16, a rear relatively shallow open end 17 and `a 4front 4relatively Y deep closed end 18, the-.'opposite ends 17' and `155 `18 of substantially different depth being provided by the sloping or inclined top 16. The front endwall 18 is provided withan opening 'Y 21, which may be of a width equal to-that of wall 18 and is preferably ofthe relative .w

height indicated with the bottomthereof con-` forming to the inner surface of the bottom wall 14. p The opening 21 may be provided-in any suitable manner but preferably a portion 'of the-material of Wall 18 is beat inwardly i455 parallel with bottom wall`l4'aslindicatedat l22 providing a guide forl a purposellaterw referred to. `The front end wall 1'8xprojects laterally outwardly of opposite sides 15 providing flanges 23 for a purpose later described. 'f7.0

vEach side wall 15is provided with a hole24 Vadj acent the junction of top wall16 and front end wall 18 as indicated in Figures 2 and 3 e for a purposelater described.

Y The section 13 is a substantiallyshallow.t Ll m7,5 Y

shaped casing member of awidth substan tially equal to that of the length of` opening 21 or the distance between sidewalls =15` of section 12.' Thesection "13 comprisesa por- 12 through opening 21 in wall 18 there-of` and adjustable relativetosection 12, the portion The section 13 further comprises a portion 27 rightiangularly disposed relative to portion 26; y The i section'13 is open at opposite ends thereofor at the free `ends ofportions 26 `and 27,fthe open end of portion 26 providing communication between sections 12 and `lvand `the open end of `portieri 127` providingV for theadmission of airto be'heated into section 13 and thence through section 12F in a-Inanner hereinafter more fully described. `The portion 27 of section 13 preferably hasthe front wall thereof cut awaya'substantialfdistance from the freeopen end thereof as indicated at 29 for az'pui'pose laterdescribed and the back and side `walls of portion27 oppositethe cut away front wall portion. `are provided-with a'plurality of air admissionholes 31. l

of room air through the oven O for uniformy ly and quickly heating the air, the oven door is opened as indicated in Figure 3 and section 12 of the heating'device 11 is insertedwithin the oven O with the bottom wall 14 thereof resting on the bottom wall of the oven and section 13 rests with the portion 26 thereof on the horizontally disposed inner wall of the oven, the portion 26 being adjustable relative to vsection 12 by loosely projecting portion 26 within opening 21 providing for fitting the device with ovens having different height doors, and the portion 27 of section 13 being disposed vertically with the end there of preferably resting on the floor as indicated in Figure 3.

The section 12 of device 11 is of a width such that the side walls 15 thereof will fit within the side walls of oven O, and due to the existence of different width ovens, the flanges 23 which engage the oven externally thereof adjacent the margins of the door will assure complete closure of the oven from the bottom thereof to the top of front wall 18`of section 12.` v

The sectionv 12 is formed of such length and height that in the applied'position there# of a substantial space represented at 33 is provided between the inner end of section 12 and the back wall of oven O and a relatively shallow opening is provided above front wall 18 of section 12fthe full width of oven O as 'represented Vat 34. l

dicated in Figure 3,'the cooler air adj acentv the floor will enter the open end of portion 27 through the cut away'portion29 and holes'31 and will flow upwardly Vand inwardlythrough horizontal portion'26 of section 13, into section 12. 1 The air entering section 12 will for the most part iiow through the shallow open rearend 17 thereof and outwardly of oven O through opening 34 in an upward course due to the angular outerw-all of section 12. The air in circulating through oven O will betsubstantially heated and due to the y continuous circulationof airin the manner indicated vfrom adjacent the floor, through the heated ovenand outwardly in an upwardly deflected direction into the room, the air within the room will be rapidly and uniformly heated by constantly admitting the colder air adjacent the floor into the heated oven and discharging same into the room.

Due to the formation of section 12 some heated air will become trapped in the upper front angular portion of section 12 which is permitted to escape into the room through holes 24 as indicated by the arrows in Figure 3.

The bottom wall 14 of heater section 12 may if desired be omitted thus giving a better thermal contact between the circulating air and the bottom of oven O.,

While the portion 27 of'heater section 13 preferably is of a length such that the free end thereof rests on the floor in applied positionof device 11 as indicated in Figure 3, the portion 27 may be of such length-that the free end. thereof will .be suspended slightly above the floor in which instance it will not be necessary to provide the cut away portion 29 and holes 31 but the air will directly enter the open end of'the'porti'on 27.

The sections 12 and 13 may beconstructed of variousV sizes thus providing heating devices 11 adapted for diderent sized ovens.

/Vhen it is desired to use the device, the oven door is opened as indicated in Figure'3 which isa common Vpractice in cold'mo'rnings in order to' rapidly 'heat the kitchen as well as adjoining communicating rooms andthe device 11 is applied* as indicated. in Figure3 with section 12 disposed within .oven O and section 13 providing an airv conduit from adjacent the floorV to the front end of section yl2 disposed with portionv 26`thereof resting on the oven door and portion 27 thereof eX- tending vertically toward the floor.

When the device isvno longer required it is removed from oven: O and stored away and due to the slidable connection between sections 12 andY 13 substantially little storage space is required for the heating device.

From the foregoing disclosure it will be seen that a deviceisprovided whereby a room can be quickly and uniformly heated by removablea'ssociation of the device with an oven and that the device is simple in construction, cheap of manufacture and can be quickly installed or removed thus well adapting it to the use for which it is intended.

iVhile l have disclosed but a single-specilic embodiment of my invention, such is to be considered asillustrative only and not restrictive since the Vscope of the invention is defined in the subjoined claims rather than by the foregoing specific disclosure.

What I claim and desire to ,secureV by United StatesLetters Patent is 1. A heating device for removable connection with an oven comprisinga casing' section adapted forldisposal within said oven; and an airY conveying sectionV communicating with said first casing section; said conveying section providing' a. conduit for admitting air from a point substantially below said oven into said first casing section; and said first casing section provided with means for effecting an upward deflection of heated air from within said oven.

2. The construction defined in claim 1 in which said conveying section embodies angularly related portions; one of said portions adjustably connected with said first casing section and adapted for support on the door of said oven.

8. In combination with an oven; a casing section removably disposed in said oven; said casing section provided with a rear open end in spaced relation to the rear wall of said oven; said casing section provided with a closed front wall partially closing the opening into said oven for providingr a substantially shallow opening into said oven adjacent the top thereof; said casing section provided with `an inclinedouter wall between said rear open end and said closed front wall; and an air conveying section communicating with said first section for directing air from a point substantially below said oven into said casing. y

4. The construction defined in claim 3 in which saidconveying section comprises an L-shaped conduit member having one leg,r thereof slidablv disposed in said casing section and the other leg thereof adapted to extend into proximity to the iioor supporting said oven. l

In testimony whereof I aiiix my signature. A
